Question

3. Design the braced column (300 x 300 mm) of the ground floor as shown in Fig. Q3. Assume the minimum cover to the 10 links is 20 mm and φ32 longitudinal reinforcement is used. The materials strengths are fau 30 N/mm and fy 460 N/mm'. The base of the column is not designed to resist moment. The axial force in the column N- 2500 kN and the moment about Y-Y and X-X at the top of the column is 30 kN-m and 60 kN-m, respectively. (1) Determine if the column is short or slender. (2) Design the area of symmetrical reinforcement for the column section. (7 marks) (K-l for conservative design in case of slender column) (13 marks) 5000 First floor 175 slab 500 Ground floor Column: 5500 300x300 mm Unit mm!
